Operating Manual

Luminometer

I Overview

UT380 series luminometer has two models: UT381 and UT382. UT380 series luminometer is a kind of digital meter applying high-precision digital visible light sensor and 8-bit microprocessor processing data.

Illuminance: Illuminance means the luminous flux received on each unit area of illuminated object, with adopted unit of foot candle (12 inches make 1foot) in Britain and USA and meter candle in Europe. 1 foot candle means the illuminance received on the surface from the direct 1 candle light source with 1 foot away from the illuminated surface, abbreviated as FC. In the same way, 1 meter candle means the illuminance received on the surface from the direct 1 candle light source with 1 meter away from the illuminated surface, abbreviated as Lux. UT380 series can test illuminance within 0 20,000Lux , and UT382 can be connected with PC to realize real-time data storage and analysis, and the data recorded in luminometer can be transmitted to PC to analyze, print and record, etc.

• The luminometer (UT382) communicates with PC using USB wire and your PC must have a USB port. See Figure 4 for the connection diagram.
• When connecting UT382 to the computer, you cannot operate any functional buttons during transmission.

6. Illuminance measurement

• In process of measuring illuminance, the sensitive mirror must be perpendicular to the measured illuminating source to ensure accuracy of measured data..
• If distance between measured illuminating source and illuminometer, measuring position, angle or environment is different, then the measured data will be different; because the intensity of light varies with change of distance, position, angle and environment.
• Make sure there is no scratch or dirt on sensitive mirror of luminometer, or the measured data won't be accurate.
• When the illuminance exceeds the measuring range of the luminometer, "OL" sign will be displayed.
• After completing measuring, cover the sensitive mirror with cap to avoid scratch on sensitive mirror and keep it clean.
